This invention relates to memorandum devices.

It has heretofore been proposed to provide wrist watches with a memorandum block so that memoranda or notes can readily be jotted down at any time. Memorandum devices are also known arrange to be worn like watches on the arm. In known wrist watches having a memorandum block, however, only one half of the watch case could be used for notes, and the surface usable for memoranda was too small for the device to be of any servicable use in practice. In addition the leaves or sheets separated from the block were readily lost. To carry a separate watch is, under" certain circumstances, troublesome and inconvenient and necessitates the sleeve being turned back too far when memoranda have to be noted down or the watch is to be viewed.

The present invention has for its object to provide an improved construction of memorandum device to which these defects are not attached.

To this end the improved memorandum device according to the invention comprises a case having a hinged journaled removably in the two ends of the case, and a memorandum band or strip extending between the rollers, which band is to be wound from the one and on to the other roller while moving over a support. "When the lid or cover is opened for making notes on the band the entire area between the two rollers is at disposal for notes. When this area has been written on, a fresh part of the band can be used after turning one of the rollers. The part carrying notes is well preserved on one roller and thus cannot get lost.

Preferably the rollers of the band are exchangeable. Conveniently, each roller is journaled at one end in a spring and at its other end in a slot in the side of the casing by means of a pivot pin having a head serving to rotate the roller. The headed pivot a cone that enters a conical recess in the side of the casing. Moreover, according to another feature of the inven- 1930, Serial No. {150,302,1and in Switzerland July 13, 1929.

device as well as a wrist p lid or cover, rollers tion' the support under the band may be selfluminous.

One embodiment of the invention is diagrammatically illustrated by way of exam ple inthe-accompanying drawing, where-' 1n Figure 1 is a lan view of the device, Figure 2 is a side elevation thereof,'and Figure 3 is a cross-section taken on the v lineflIIT-III in Figure 1 but showing a" modified mount for one end of a roller; Figure 4 is a cross-section taken on the line IV-IV in Figure 3, the roller being. omitted. 1 Like-reference characters designate like arts in all the views. l

A case 1 that is rectangular as viewed in plan has a concave rear wall 2, two chambers 3 and 4 at its ends, and a lid or cover hinged'at 5 to the body of the case. watch 7 having a dial 8 of rectangular or other desired shape is carried by the'lid 6. A roller 9 is removably journaled in each chamber 3 and 4. The one end of each roller has a pivot carries a collar 11 and a cone 12 connected to a pivot pin 1E) having a head 14. The pin 10 extends through a recess or hole in a leaf spring 15 fastened to the middle of the inner side of a longitudinal wall of the body of the case, which spring presses the cone 12 into a conical recess in the opposite longitudinal wall 16 ofthe case, so that the roller is held frictionally against rotation. The pin 13 lies in an upwardly opening slot 17 in the wall 16, and the cone 12 also prevents the roller from falling out of the case when the lid is open. When it is desired to remove the rollers 9,after the lid has been opened the heads 14 are pressed inwards until the cones 12 leave their recesses in the wall 16 of the case, whereupon the rollers can be lifted away. v

A band 18 of paper, film or the like is Wound on the two rollers and extends between the latter over a smooth fiat face 19 on the bottom wall of the case. The band 18 serves for receiving notes or memoranda which can be applied to it after the lid 6 has. been opened. By turning the two rollers pin 10, and the other end ries a layer of a radio-active substance, so

the band 18 can be Wound up on one and ofl the other. When the band is full of notes it can be removed with the two rollers and be replaced by a new one.

The supporting surface 19 preferably carthat it is self-luminous. It isthen possible to write notes in the dark without external illumination of the surface that is being Written upon, as the band is of course very thin and therefore translucent, so that the self-illumination entirely suffices for Writing in the dark.

The modified construction illustrated in Figures 3 and 4 differs from the device described above with reference to Figures 1 and 2 only in that instead of one leafspring arranged on one longitudinal wall of the case to provide two bearings, one for each roller 9, two. upwardly bent-leaf springs 15 of L shape are fixed one on the bottom of each end chamber 3 and 4:1

The described memorandum device enables. notes to be jotted down at any time as the describedwatch when worn on the wrist is always at hand and can be worn like an ordinary watch Without occupying any appreciable additional space.

We claim 1- 1. A memorandum device of the character described, comprising ahollow body portion provided with sides and inwardly curved back, rollers mounted between the sides for carrying a note band, a platen disposed-in said body midway between the back and' front to support thenote band between the rollers, and a cover mountedvto close over the front of the body to; provide space for the reception of a watch.

2. A memorandum device, as claimed in claim 1, in which the front surface of the platen beneath the note band is'coated'with luminousmaterial to illuminate the note band disposed .thereover.
